Add me to the list of those happy converts. Had it installed on Saturday when the new rear tire was installed. Could feel the difference as I was pulling out of the parking lot. Best $200.00 I've spent on the machine since I bought her. No more eyeball bounce.

 

That is a great upgrade I sure like mine! If you ride with guys that have 06's you can now let them lead and your always in the right gear, no more 3rd 4th and back ,down to 2100 is fine with IDS.

 

I put one on my 99 ultra with my 103 and six speed I enjoy no jerking.

 

07 Ultra: I added one also with new rear tire at 9,200mi. I honestly can say I didn't notice any improvement other than a fresh tire "feel". I already had loud exhaust so I'm not talking about any difference in the whine or clatter.

 

I did the same on my 07 Ultra at 8500 miles. Had no clatter or whine. No noticeable difference now.
